Manufacturing method of human body equivalent simulation target applied to explosion multi-physical field damage effect assessment

Abstract

The invention provides a manufacturing method of a human body equivalent simulation target applied to explosion multi-physical field damage effect assessment. A target manufactured by adopting the method is arranged in an explosion multi-physical load effect area so as to directly respond different explosion harm element damage properties. The target manufactured by adopting the method is a human body equivalent simulation target with organs and is a human model which has endoskeletons and internal tissue organs being more similar to geometrical dimension and material dynamic response of a real structure; the target can be formed and applied to a human body equivalent model which is arranged in the explosion multi-physical field load effect area and can directly respond the different explosion harm element damage properties; and the target can improve and perfect research systems such as explosion hazard assessment, personnel deadly or incidental damage mechanism, protection performance assessment of explosion preventing / eliminating equipment and the like in the public safety field; and moreover, the system checks the multi-physical field load biological damage properties and the protection performance of the explosion-preventing equipment.

Description

technical field [0001] The invention relates to a method for making a target, in particular to a method for making a human equivalent target for evaluating the damage effect of human organs under the action of explosive multi-physics field loads. Background technique [0002] Explosion multiphysics is usually accompanied by loads such as shock waves, fragments, and mechanical work, which can cause damage effects such as impact injuries, fragment injuries, and throwing injuries to personnel targets. In military confrontation, personnel, as an important part of the combat system, play a decisive role in the display of combat effectiveness, and are also the most vulnerable factor in the entire system. For example, under the action of overpressure, negative pressure and dynamic pressure, the shock wave will produce pressure difference, implosion effect, rupture effect, etc. in the solid and hollow organs, which will cause damage to the internal organs of the human body; the high...

However, there are large differences between pine boards and human tissues and organs, and there are also great differences in penetration damage performance of pine boards in different regions and with different storage times.

In addition, traditional living animals are used as human equivalent targets, such as SD rats, big-eared white rabbits, adult beagle dogs, goats, pigs, rhesus monkeys, etc., although they have similar anatomical structures, equivalent mechanical properties, and physiological functions. Equivalent and equivalent damage effects, etc., but the differences in individual tissue structures of different animals are more prominent, so there are differences in circadian rhythms compared to the human body (for example, the shock wave damage to the lungs is closer to that of the human body, and the fragments penetrate Sexual injuries are closer to pigs, sheep or dogs)

At the same time, there are limited test samples, difficulties in obtaining anatomical observation and pathophysiological test data, and a large number of live animal tests are likely to cause international ethical issues

[0004] Although ballistic gelatin can better reflect the dynamic response of human muscle or other viscoelastic tissues when they are impacted by fragments at high speed, it often ignores the combined damage to human bone structure caused by shock waves and mechanical work loads in the multi-physics field of explosions. At the same time, since ballistic gelatin can only be stored in an environment of 4°C to 10°C, it is less suitable for tests at real ambient temperatures

There is also the Hybird dummy model used in the field of automobile collisions. It can reflect the mechanical characteristics of the human target after a severe impact in terms of counterweight, mass distribution, and different sensor interfaces. However, due to its high cost, it cannot directly Arranged in the explosion multi-physics load area, in particular, it cannot be hit by secondary projectiles such as fragments, so as to avoid unnecessary damage, and its limited test sample size cannot reflect the effects of multiple measuring points at different explosion distances.
